When they watched the footage back, they were shocked to find that Galina Sicheva, the boy's nanny, had been beating him and locking him in a room. The boy was seen crying and screaming as he was locked away for long periods of time as punishment.
His mother, Julia Gotz, 32, called the police but the nanny claimed she had simply been trying to make sure the boy grew up correctly.
She said: 'I love this little fellow as if he was my own son.'
But mother Julia said that the nanny seemed like a different person to the one they saw with their son when they were around, and rejected her reasoning for treating the child in the rough manner she did.
